Question about Showing/ Hiding a container

I have just started learning js roughly a month, month and a half ago. I am not the greatest but I learn fast.

I am trying to show, or uncollapse a container box only if a certain field from my database contains data.
What would be my best way to go about this. Nothing special about the field, just a text field. The container box has text in it, but nothing special.

My biggest issue is pulling the data from the database, I thought I had a solid understanding and I do not.

I should make it clear that I am trying to collapse this container if a REFERENCE field is empty.

A sample would be great, obviously I would like to learn how to do it, not just copy and pasta.

Thank you,
Jared

Hi Jared!

Have you looked at the isNotEmpty function in Wix Data Query?

You can query your collection (also using include(). [and include the reference field] for example).
The if the retrieved object doesn’t contain this field, hide()/show() the element.

Fields that are empty usually have falsy values. So you can set an if statement to exclude the value if it is either undefined or ‘’.

Thank you! I actually figured out what I needed too! I was over complicating how to do what I needed to do. But I will read up on all those links you gave me, in case I need them for future reference. I appreciate your time!
